Agrocybe pediades, commonly known as the common fieldcap, common agrocybe,[1] or hemispheric fieldcap,[2] is a species of fungus. It can be found on grassland. It is potentially edible, but it could be confused with poisonous species, including one of the genus Hebeloma.
Taxonomy
[edit]It was first described as Agaricus pediades by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus, Agrocybe, by Victor Fayod in 1889. A synonym for this mushroom is Agrocybe semiorbicularis, though some guides list these separately.[3]
Description
[edit]The mushroom cap is 1–3 cm wide, round to convex (flattening with age), pale yellow to orangish-brown, smooth but sometimes cracked,[1] and tacky with moisture but otherwise dry.[4] The stalks are 2–7 cm long and 1–4 mm wide.[4][5] A partial veil quickly disappears, leaving traces on the cap's edge,[4] but no ring on the stem.[6] The cap's odor and taste are mild or mealy.[4]
The spores are brown, elliptical, and smooth,[4] producing a brown spore print.[5] Some experts divide A. pediades into several species, mainly by habitat and microscopic features, such as spore size. It is recognized by the large, slightly compressed basidiospores which have a large central germ pore, 4-spored basidia, subcapitate cheilocystidia and, rarely, the development of pleurocystidia.[7]
Similar species
[edit]Other similar species include Agrocybe praecox and A. putaminum.[4] Hypholoma tuberosum is also similar.[5]
Habitat
[edit]It typically can be found on lawns and other types of grassland,[8] but can also grow on mulch containing horse manure. It appears year-round in North America.[5]
Uses
[edit]This species is edible, but it could be confused with poisonous species, including one of the genus Hebeloma[9] and various little brown mushrooms.[1] Some field guides just list it as inedible[3] or say that it is not worthwhile.[6]
